To all whom it may:concem'u;v

Be it known that 1, WILLIAM H. DEAN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented new and useful Improvements in Window-Cleaners Brackets, ofwhich the following is a specification.

This invention is an improved window cleaners bracket providing a framefor arrangement on the inner side of a window I and a bracket armextending outwardly from the frame and to correspondingly extend outthrough the window and a seat on said bracket arm to enable a person tobe safely seated on the outside of the window while cleaning the sameand avoid all danger of falling and being injured or killed, the objectof the invention being to provide an improved device of this characterwhich is light, cheap and simple, which may be readily carried fromplace to place and which may be readily arranged for use in a window.

The invention consists in the construction, combination and arrangementof devices hereinafter described and claimed.

In the accompanying drawings Figure l is an elevation of a windowcleaners bracket constructed in accordance with my invention, showingthe same set up and arranged for use at a window, the window frame and aportion of the wall in which the same is located being indicated insection.

Fig. 2 is a vertical sectional view of the same showing the bracket infolded position.

Fig. 3 is a front or inner side elevation of the bracket, showing thesame set up and arranged for use.

In accordance with my invention I provide a vertical frame 1 adapted forarrangement on the inner side of a window and comprising a pair ofupright bars 2 and a pair of cross bars 3-4, the former near the upperends of the bars 2 and the latter at a suitable distance from the lowerends thereof. These cross bars are rabbeted on the upright bars and aredetachably secured thereto by means of bolts 5, this constructionadapting the parts of the frame to be readily disassembled when desired.At the lower portions of the upright bars 2, and on the inner sidesthereof, are bracing and supporting knees 6 which may be of any form orofthe form here shown. The bars "2nareprovided on their inner sides,near their upper ends, with bearings S for the pivot portions 9 of apair of hooks 10, these hooks being adapted to engage on the outer sideof the wall at the upper side of the window and their pivot portionsbeing connected by an eccentrically arranged rod 11 which has an arm 12.A cord 13 is attached to this arm and a pull on this cord serves to turnthe hooks into engagement with the upper part of the window.

Bearings 14 are also secured on the inner sides of the bars 2 at a pointa suitable distance from their lower ends. A rock shaft 15 is mounted inthese bearings and has hooks 16 to engage on the outer side of the wall,at the sill or base of the window frame and is also provided with anoperating arm 17 by means of which said rock shaft may be readily turnedto move said hooks 16 to engaged or disengaged position. The frame 1 issufficiently long to extend from the floor to a point above the windowso that the frame can bear against the wall, on the inner side thereof,but the width of the frame is less than that of the window and the framemay be arranged either in the center of the window or adjusted to eitherside thereof as desired.

A bracket 18 which is substantially U- shaped and is preferably made ofiron or other metal has its arms 19 pivotally connected to the innersides of the upright'bars 2 of the frame by means of pivot bolts 20.This bracket is hence adapted to be arranged in a horizontal positionextended out from the window and to bear on the base thereof or thebracket may be turned upwardly and arranged close to the frame 1 tocompactly dispose the device for portage from window to window or placeto place. At the outer end of the bracket is a seat 21 on which thewindow cleaner may sit in safety while cleaning the outside of thewindow and the arms of the bracket are provided with downwardlyextending clamping arms 22 to bear against the outer side of the windowsill.

My improved window cleaners bracket may be made of any suitable size andof any suitable material. It is light, strong and cheap and may bereadily carried from place to place and set up and used. Its useobviatesaH danger of falling and makes it entirely safe to clean Windowsof tall buildings on the outside. 4

Having thus described my .invention,fI

In a device ofthe class described, a frame for arrangement Vertically onthe inner side of a window, a bracket carried by the frame to projectout through the Window, a rock 10 shaft mounted in bearings on theframe,

hooks on the rock shaft to engage on the outer, side of the Wall and alever to turn said rock shaft to engage or disengage the in presence oftwo Witnesses.
